NSLinkAttributeName not working in UITextView

Question

I am working on an iOS application and I am using Swift. I want to make the word clickable and open some URL (currently www.apple.com) when this word is clicked.

I use the following code, but for some reason it does not work.

func setDescription(description: NSAttributedString)
{
    let descriptionRect = CGRectMake(10, 50, self.bounds.size.width - 20, self.bounds.size.height-20)
    let descriptionView = UITextView(frame: descriptionRect)
    descriptionView.editable = false
    descriptionView.selectable = false
    descriptionView.attributedText = description
    descriptionView.delegate = self
    descriptionView.font = UIFont(name: "Helvetica", size: 14)
    NSLog("%@", descriptionView.attributedText)
    self.addSubview(descriptionView)
}

func textView(textView: UITextView, shouldInteractWithURL URL: NSURL, inRange characterRange: NSRange) -> Bool {
    NSLog("In text view delegate")
    return true;
}

Below the fragment takes a string and forms an attribute string with the first 5 characters holding NSLinkNameAttribute. Then I called the setDescription function to add this attribute string to the TextView.

            let mutableAttrString = NSMutableAttributedString(string: attrString1)
            let linkURL = NSURL(string: "http://www.apple.com")
            mutableAttrString.addAttribute(NSLinkAttributeName,value: linkURL!,range: NSMakeRange(0, 5))
            wordDetailView.setDescription(mutableAttrString)

When I click on a word that has a link textview attribute, the delegate is not even called !!!! Can someone please help me why it does not work and how it works.

Thanks.
